Things You'll Need:
- Petroleum jelly
-
Step 1
If your birdhouse or feeder is on a metal pole, apply petroleum jelly to the pole about a foot from the bottom of the house or feeder. You will need to apply a thick layer completely around the pole, at least 2-3 inches wide.
-
Step 2
If your birdhouse or feeder is on a wooden post, apply petroleum jelly to the post about a foot from the ground and about a foot from the bottom of the house or feeder. You will need to apply a thick layer completely around the post, at least 2-3 inches wide.

Step 3
After applying, be sure you have completely filled any cracks or crevices, especially in wooden posts. If your post is attached to a building, fence, or anything else accessible to ants, be sure to apply a protective layer about a foot away from the house or feeder in each direction.
